This is already done:
- VPC Network -> VPC Networks
- Firewall

Need to set up this again:

Compute Engine -> VM Instances

CP:
ssh -i ~/.ssh/lfclass student@34.78.179.101 

Worker:
ssh -i ~/.ssh/lfclass student@34.78.100.81


On both nodes:

wget https://cm.lf.training/LFD259/LFD259_V2024-02-22_SOLUTIONS.tar.xz --user=LFtraining --password=Penguin2014

tar -xvf LFD259_V2024-02-22_SOLUTIONS.tar.xz

On CP node:

find $HOME -name k8scp.sh
cp LFD259/SOLUTIONS/s_02/k8scp.sh .
bash k8scp.sh | tee $HOME/cp.out

On Worker node:

find $HOME -name k8sWorker.sh
cp LFD259/SOLUTIONS/s_02/k8sWorker.sh .
bash k8sWorker.sh | tee $HOME/cp.out


kudeadm step:

The kubeadm joinstatement can be found nearthe end of thekubeadm initoutput on the cp node. It should also be in the filecp.outas well. Your nodes will use adifferent IP address and hashes than the example below. You’ll need to pre-pend sudo to run the script copied from the cp node.  

student@worker: ̃$ sudo kubeadm join --token 118c3e.83b49999dc5dc034 \10.128.0.3:6443 --discovery-token-ca-cert-hash \sha256:40aa946e3f53e38271bae24723866f56c86d77efb49aedeb8a70cc189bfe2e1d


Bash completion:

student@cp: ̃$ sudo apt-get install bash-completion vim -y
student@cp: ̃$ source <(kubectl completion bash)
student@cp: ̃$ echo "source <(kubectl completion bash)" >> $HOME/.bashrc

Add taints:

student@cp:~$ kubectl taint nodes --all node-role.kubernetes.io/control-plane-


Needed for Lab 5: (Can get this from lab 3)
Need to tag and push the image

student@worker: ̃$ find $HOME -name local-repo-setup.sh
student@worker: ̃$ cp /home/student/LFD259/SOLUTIONS/s_03/local-repo-setup.sh $HOME
student@worker: ̃$ chmod +x $HOME/local-repo-setup.sh
student@worker: ̃$ . $HOME/local-repo-setup.sh       # dot <space> scriptname to set correct variables
student@worker: ̃$ sudo podman pull $repo/tagtest # if needed export repo=10.97.40.62:5000
sudo podman tag simpleapp $repo/simpleapp
sudo podman push $repo/simpleapp
